Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

The mounting platform 1 is used to install a structure that supports the side support plate 6. The front and rear ends of the mounting platform 1 are connected to the side support plate 6 through a supporting device. The bottom of the mounting platform 1 is connected to the bottom plate 3 through the lower support seat 2. The bottom plate 3 is installed at the bottom of the foundation pit, so that the mounting platform 1 is separated from the foundation pit by one end. The rear end of the side support plate 6 is attached to the side wall of the foundation pit. The rear end of the side support plate 6 is provided with multiple water inlet holes 14. The structure of the water inlet holes 14 is a large outer radius and a small inner radius. The inside of the side support plate 6 is provided with a drainage channel along the inner diameter outlet of the water inlet hole 14, and a drainage pipe 15 is connected along the bottom of the drainage channel. The soil accumulation trough 16 opened at the lower end of the rear side of the side support plate 6 is used to accumulate water and soil in the foundation pit, and the drainage trough 17 is used to discharge water accumulated to a certain height. During use, the base plate 3 can be first fixed to the bottom of the foundation pit, and then the hydraulic rods 5 at the front and rear ends of the telescopic mounting platform 1 and the inner rod 10 inside the sliding outer rod 11 push the side support plates 6 on both sides toward the foundation pit wall. After the side support plates 6 are attached to the foundation pit wall, they are reinforced with side anchors 24 and the positions of the outer rod 11 and inner rod 10 are fixed. When water in the foundation pit side wall seeps, it can enter the interior of the side support plates 6 through the water inlet holes 14. Soil and some water can accumulate in the soil accumulation trough 16 at the lower end of the drain pipe 15.

When the water flow in the soil accumulation trough 16 accumulates to a certain height, it can be discharged from the drainage trough 17 and sent to the side end of the base plate 3 for drainage treatment. If the drainage trough 17 is opened for drainage, it means that the foundation pit wall is seriously seeping, and the construction personnel can deal with it in time.

When the mounting platform 1 activates the hydraulic rod 5 to push the side support plate 6, the auxiliary support rod 22 at the side end of the mounting platform 1 will rotate inside the mounting seat 23 and the slide seat 21, and push the slide seat 21 to slide inside the slide groove 19. The auxiliary support rod 22 and its adjacent structure can provide auxiliary support, improving the stability of the side support plate 6 during movement.
[0030] Reference Figure 1 The front end surface of the side support plate 6 is fixedly connected with a positioning plate 7, and the internal thread of the positioning plate 7 is connected with a side anchor 24. The positioning plate 7 is used for positioning, which makes it convenient for construction workers to nail the side anchor 24 for reinforcement into the foundation pit wall.
[0031] Reference Figure 1 The bottom of the base plate 3 is threadedly connected with a lower anchor 4. The lower anchor 4 is used to reinforce the base plate 3 and install it on the surface of the foundation pit.
[0032] Reference Figure 1 and Figure 2 The side end of the positioning plate 7 is fixedly connected to the upper rotating seat 8, and the inner sleeve rod 10 is rotatably connected inside the upper rotating seat 8. The surface of the inner sleeve rod 10 is slidably connected to the outer sleeve rod 11. The top of the outer sleeve rod 11 is rotatably connected to the lower rotating seat 9, and the lower end of the lower rotating seat 9 is fixedly connected to the mounting platform 1. When the hydraulic rod 5 pushes the side support plate 6 to move, the inner sleeve rod 10 inside the outer sleeve rod 11 will slide toward the front end under the pulling force of the side support plate 6. At the same time, the inner sleeve rod 10 and the outer sleeve rod 11 will rotate inside the upper rotating seat 8 and the lower rotating seat 9. The inner sleeve rod 10 and the outer sleeve rod 11 serve as auxiliary supports for the side support plate 6, and the use of two auxiliary support structures improves the stability of the device during movement.
[0033] Reference Figure 2 The side end of the inner sleeve rod 10 is provided with a plurality of thread grooves 12, and the side end of the outer sleeve rod 11 is threadedly connected with a limit screw 13. When the side support plate 6 is attached to the foundation pit wall, the position of the inner sleeve rod 10 and the outer sleeve rod 11 can be fixed by the limit screw 13.
[0034] Reference Figure 1 and Figure 3 The side ends of the soil accumulation trough 16 are fixedly connected with side baffles 18. The side baffles 18 are used to block the soil in the foundation pit walls on both sides of the side support plates 6, avoiding directly falling into the inside of the soil accumulation trough 16, affecting the judgment of the construction workers on the accumulation and seepage of water.
[0035] The present application discloses a support device for a deep foundation pit in a building construction project. The implementation principle is as follows: During installation, the base plate 3 is first reinforced and mounted to the foundation pit surface using lower anchors 4. The side support plates 6 on either side are then pushed toward the foundation pit wall by hydraulic rods 5 at the front and rear ends of the telescopic mounting platform 1 and inner rods 10 within the sliding outer rod 11. When the mounting platform 1 activates the hydraulic rods 5 to push the side support plates 6, auxiliary support rods 22 at the side ends of the mounting platform 1 rotate within the mounting seat 23 and the sliding seat 21, pushing the sliding seat 21 to slide within the chute 19. The auxiliary support rods 22 and their adjacent structures provide auxiliary support, improving the stability of the side support plates 6 during movement. When the hydraulic rods 5 push the side support plates 6, the inner rods 10 within the outer rod 11 slide toward the front under the tension of the side support plates 6. Simultaneously, the inner rods 10 and outer rod 11 rotate within the upper and lower rotating seats 8 and 9. The inner sleeve rod 10 and the outer sleeve rod 11 serve as auxiliary supports for the side support plate 6, and the two auxiliary support structures are used to improve the stability of the device during movement. After the side support plate 6 is attached to the foundation pit wall, the position of the inner sleeve rod 10 and the outer sleeve rod 11 can be fixed by the limit screw 13. The side anchor nails 24 used for reinforcement are then nailed into the foundation pit wall. When water in the foundation pit side wall penetrates, it can enter the inside of the side support plate 6 through the water inlet hole 14, and the soil and part of the water can accumulate in the soil accumulation groove 16 at the lower end of the drainage pipe 15. The structure of the water inlet hole 14 with a wide outside and a narrow inside allows the seepage water to flow into the drainage pipe 15 for discharge. When the water flow inside the soil accumulation groove 16 accumulates to a certain height, it can be discharged from the drainage groove 17 and sent to the side end of the bottom plate 3 for drainage treatment. When drainage is opened at the drainage groove 17, it means that the foundation pit wall is seriously seeping. At this time, the construction personnel can promptly deal with the accumulated water inside the foundation pit. This device has a simple structure and adds multiple sets of auxiliary support devices to the support device to improve the stability of the device during movement. During use, it can guide and collect seepage from the side walls of the foundation pit, making it convenient for construction personnel to observe and handle the water.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
